Mark Cuban issued a warning to billionaire counterpart Elon Musk about relying on former President Donald Trump: He won’t be there for you.

In reply to a post on X by Musk, Cuban said he should be careful about aligning himself so closely with the Republican presidential candidate. If he comes to Trump asking for a favor, he will surely find out where his loyalties lie, Cuban added.

“You have been a loyal, faithful soldier for him. You have supported him politically with 10s of millions of dollars,” Cuban wrote. “Then, at the point you need him the most, you will find out what so many before you have learned, his loyalty is only to himself.” 

Although just a few years ago, Musk said Trump should “hang up his hat & sail into the sunset,” the Tesla CEO has changed his tune lately.

Musk has thrown his full support behind Trump and has said he would accept a role in his administration. When he interviewed Trump in August, Musk also pitched him on the creation of a “government efficiency commission” to reform the federal government, and Trump has said Musk could be good to lead such a commission.

At the same time, Cuban has become one of Vice President Kamala Harris’s most vocal supporters. Amid attacks from the right, Cuban has defended Harris as “pro-business” and has said he would put his name in the running for commissioner of the Securities and Exchange Commission.

The November presidential election has pitted some of the country’s wealthiest people against one another. Apart from Musk, Trump and the Republicans also count on the support of PayPal cofounder Peter Thiel and Cameron and Tyler Winklevoss of The Social Network fame. Harris and the Democrats, meanwhile, have the support of LinkedIn cofounder Reid Hoffman and philanthropist Laurene Powell Jobs. 

Another Trump supporter, investor David Sacks, replied to Cuban’s post saying Cuban was projecting, revealing how he thinks about politics. Cuban replied that this was not the case.

Classic case of projection. You’re describing how you think about politics.

“What I said has nothing to do with politics,” Cuban said.
